i To all whom it may concern:

ledo, county of Lucas, ancIState'of Ohio,

have invented certain new and useful Improvements 1n Tools for Removlng Shaft- Thisinvention relates to improvements in tools for removing shaft couplings,

The principal object of this invention 1s to i provide an improved Qtool, which may" be by the devices and means described in the very conveniently andelfectively used to remove a' shaft coupling, such as is used to...

couple the propeller shaft to the transmission mechanism of a motor vehicle.

Further objects, the objects relating to economies of manufacture and details of construction, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention following specification. My invention is clearly defined and pointed out in the appended claims.

A structure constituting a preferred em bodiment of my invention is illustrated in the accompanying drawing, forming a part of this specification, in which 1 Figure I is a view in side elevation of a tool constructed in accordance with my invention, showing it applied in position for removing the shaft coupling from a pro peller shaft. p

Fig. II is a vertical, sectional view, taken substantially on the line IIII of Figs. I and III. 1

Fig. III is a detail, sectional view, taken substantially on the line IIIIII of Figs. I and II.

In the drawings, similar reference numerals refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing, I have shown the casing 10 of the 1 Specification of Letters Patent.

12, is provided with grooves or ways, in which the splines 13 and 14 are disposed, and said coupling 15 is also provided with radially extending openings 16, in which set screws are normally insertedfor securing the coupling 15 inplaceon the shafts to couple them together. I invention has to do with a tool by means of which thecoupling 15 can beeasily andquickly removed so as to disconnect the shaft 11 from the transmission shaft 12. The set screws which are normally disposed inthe opening 16 are first removed. "The tool comprises a ring 17, which is provided with laterally extending ears 18. The ring 17 carries the radially extending set screws 19,-the ends of which are adapted to engage in the ends of the openings 16, in which the set screws for securing the coupling 15 to the shafts 11 and 12 are normally disposed. The ring 17 is slipped over the coupling 15, the opening in said ring 17 being large enough to permit of its being placed over the coupling 15 and theset screws 19 are screwed up until the ends are firmly seated in the openings 16 of the coupling 15. The ears l8 carry the set screws 20, which extend parallel to the axis of the ring 17 and the coupling 15, and the ends of said set screws above, the operation of this device should be very readily understood. The drawings show the tool in position for use to remove the coupling 15. The ring 17 is connected to the coupling 15 by the engagement of the set screws 19 with the openings 16, and when the set screws 20 are turned up, since their ends abut against the casing 10, the ring 17 and the coupling 15 carried thereby will be forced away from the casing 10, thus forcing the coupling 15 off of the end of the transmission shaft 12, so that the propeller shaft 11 will be disconnected from the shaft 12. Then the coupling has been thus removed, the set screws 19 are screwed out, so that the ring 17 is released from the coupling 15 and maybe removed.

I am aware that the particular embodiment of my invention, which I have here shown and described, is susceptible of considerable variation without departing from the spirit thereof, and, therefore, I desire to claim my invention broadly, as well as specifically, 'as'indicated by the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A device of the class described, com

prising a ring, provided with a plurality of .radially extending set screws carried there- .thereof andadapted to engage said coupling; and a plurality of set screws carried by said ring extending parallel to the axis thereof, and spaced from each other circumferentially of the ring.

3. A device of the class described, comcopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

coupling; and a plurality of set screws carried by said ring at diametrically opposite points thereof, and extending parallel to the axis thereof.

4:- A device of the class described, comprising the combination of a ring provided with a pair of laterally extending ears and a central opening large enough to receive a shaft coupling; set screws extending ra- 'dially through the wall of said ring, and

, adapted to engage said shaft coupling, said set screws being disposed atdiametrically opposite points of said ring; and a set screw extending through each of said ears and parallel to the axis of said ring.

1 In testimony whereof I aflixmy signature. GRANT W. ROLLINS.
